Why does physical activity promote blood circulation?
Physical exercise is highly beneficial for health in general, and for blood circulation in particular.
- muscle contractions during physical activity act like a pump, sending blood towards the heart,
- the heart itself has a suction-propulsion action during exercise,
- your higher breathing rate during exercise helps to increase this pumping action by variations in pressure.
